if you had your plans down for your giant digital logic tv set, then unfortunately you go to look up the costs of the parts.

in single components itll cost $256,000!!!!!!! just for one crappy tv!!!

Also itll be bigger than your house, so to cut down the size to be more useable, so you have to learn how to make capacitors and resistors, mainly, everything else is optional, including diodes. and capacitors and resistors are the easiest ones to make! but you need to get into the chemistry if you want to make a camera, photo-resistors.

I just looked it up today, and its horrifying, maybe when the components are larger, the material costs come into it, and a micro capacitor actually uses less material so its cheaper - but stuff like that is not usually obtainable by the average hobbyist.

I am waiting for the time when i make own stuff with a 3d printer.

All appliance stores will go out of business.

I just order my universal printing material/ liquid over the web and
get it the mail, next day.
Down load plans for what i want to make with my 3d printer. Like a tv,
oscilloscope, radio, pistol, computer, and so.

What concerns cases, then one may consider another wonderful material, cardboard. Like, it's much better to make computer speakers from cardboard, than from plastic. They say the best material of all for telescopes and optics is cardboard, as it has the lowest thermal contraction. When painted, it is waterproof too. And, it is much more environmentally friendly, than plastic.

I have done allot of mathematics on the dynamic folding of paper:
Kirigami:
https://en.wikipedia.org/wiki/Kirigami

No, why disbelief, you have actually not even claimed anything. I let you to do the research.

What concerns me then, actually right now i programmed a pulse generator for arduino, so now for the first time i actually use the oscilloscope, to see what comes out, ehh. Well actually, with pwm and a simple low pass filter, one can make a function generator. The key is, you have a 16 bit integer, then, you choose an increment so that it corresponds to the frequency. You only increment, when it overflows it starts from zero again. Like that, it's a sawtooth wave. Then, triangular wave is made so that, when the highest bit becomes one, all bits shall be inverted. Triangular wave is most similar to sine. Always inverting it makes an inverse sawtooth wave. This, different from wavetable, enables a very fast code, thus higher frequency. So you see the stupid things i do. Get yourself this, attiny85 board from ebay, $1 with shipping, then you can do the same ;)

Looks like it is coming along nicely, their Rouncer.

I am working on my tic-tok computer.
It has a one mega byte chip on the left side of a board and a one mega
byte chip on the right side. When it hit with one clock pulse, all of
the contents in the left memory is moved into right memory.
On the next pules, all data is moved back.
The data bus will be very wide, one million + bi directional lines.
In the middle is a third chip. A ALU chip that intercepts the data when
it clocked to one side.

I am going to clock and power the whole thing with a instantaneous
collapsing magnetic field. Which is a superluminal EMP pulse.

The device that that generates the pulses is vanadium dioxide device,
switching on and off in magnetized coil, with light pulses.

Ah yes Tkoorvi - you are doing digital waveforms! doing them analogue takes less components, but I think that doing them with digital counters like your describing probably is good too.

Keghn that sounds good, but you have to roll the idea into something that works without a doubt, or you shouldnt be so confident of success.
But it sounds like a good idea, the read side to the write side, toggling.

On this new thing, hardware->

i did software for so long, had no idea how to make a computer from scratch, but the more i do it, the more i realize how not special it is whatsoever over software and algorythms, which are equally important.

hell, we always had gameboys! its no big deal.

I still have an idea, that im going to get extreme performance if i do the craftwork myself, so i continue on - this being the direction for computations per second.

Hey Keghn, check this idea out->

I have 2 copper etched pcbs with capacitor film inbetween, and I was wondering can I do as many capacitors as I want into the same film - or do i need to separate dielectric from not dielectric (i also dont know what a not delectric even is, because im only real fresh at this.) - in some kind of cell system. (for making 10 thousand capacitors in one hit.)

a capacitor can be used as a temporary bit. but this idea! i HAVE NO IDEA ABOUT!!! will the charge retain in the plastic or what?

Yes you can make a big capacitor with 2 pcb boards. Put a thin sheet
of paper or plastic rap between the two metal sides. the non conducting
boards are too thick. Ideal you want the thinnest non conductor
between the metal pates.

Yes they do make memory cell with capacitance. It is called dynamic ram.
It hold a bit for a short time so it has to be refreshed with a pules,
because the cap are not perfect, charge will leek out slowly. Dynamic
ram is refreshed with a one million Hz clock. That fast because they
very small capacitor.

Dynamic ram, in you computer right now:

https://en.wikipedia.org/wiki/Dynamic_random-access_memory

They are make big caps for energy storage called supercapacitors
They do not have the energy density of batters but what energy
you put in and take out is done with 98 percent efficiency.
And can discharge all there energy at once, if needed.

When charging,
a batters only absorb 30 of the energy . The rest is turned into heat.
And the same or worst when using them in a project or appliance.
All the energy in a batter is discharged a 100th the rate of a
supercapacitor.

Yes, the leakage is a problem but im ok theoretically because for the majority of the system, they are only supposed to be temporary, they actually just carry the logic through.

Because I have a huge issue with conductance not working for me, alone, if I separate into steps through capacitors it saves the idea without even needing a diode! (so i go through the film.)

But of course, I do need more permanent stuff as well, for the computer memory, so I havent thought about the refreshing idea yet!

Thanks for bringing it up!

I asked that really cool guy doing super capacitors if i can cheat with just one film for all the capacitors at once, and he said to the effect of he didnt know exactly but couldnt think why it wouldnt depending on arrangement of the plates.

so ill be off to the electronics store to ask stupid questions again! and get my head into pcbs, and get off the nasty old wires that break and dont connect very well, and confuse the hell out of you when it changes shapes.

Maybe try electrets, well, just a wild idea

rouncer

posted 1/2/2016 12:49

so a capacitor is a temporary electret? the same way a coil is a temporary magnet?

tkorrovi

posted 1/2/2016 16:49

Well, just heard, electrets have hysteresis, so it should be possible to use them as memory, and likely much more easily than magnets. There is one more passive component in addition to resistors and capacitors, memristors, and these are too used as memory.

I think I am going to use EPA tech for making switches in my robot skin.
They are cheap and can be made with 3D printer. And they can be
printed into the skin at the same time the skin and skin senor structures,
are put in.
Now i got to find something that can print on a small scale and a materials
to switch a fast speed.
